2001 Mars Odyssey: GRS
CGS

The
gamma sensor part of the GRS instrument suite stopped
returning data on September 7, 2009. There are no gamma
EDR, CGS, or SGS data since that event. See the ERRATA.TXT
file for details.

GRS Corrected Gamma Spectra (CGS) products are organized as a single virtual volume.
Each CGS file includes data for a two-hour time span. The products
are aggregated in subdirectories by day. The subdirectories are in turn grouped
into directories by year.

Use the links below for direct HTTP access to any part
of the GRS CGS archive. Alternatively, to search the
archive for data that meet particular criteria, e.g.
time and location, use the Mars Orbital
Data Explorer (ODE).
